Might? I catch the Docker deamon regularly to eat through a full core while no container is actually up. Also every now and then I have to manually delete all the dangling docker images because the filesystem runs out of nodes because Docker doesn't clean up after itself (although this could be on purpose, I don't know, or I'm doing something wrong...)<p>EDIT: I guess this has nothing to do with docker0, but still, docker is feasting on my battery every now and then.
docker0 is just a regular Linux bridge and there's absolutely nothing special about it.<p>I've always assumed that powertop was mis-reporting power usage for those decidedly non-physical interfaces.<p>Therefore, the author's reported decrease in power usage surprises me. Can anyone reproduce/explain this?
Is it anything to do with this issue, where Docker is waking the cpu from sleep too often?<p><a href="https://github.com/docker/for-linux/issues/382" rel="nofollow">https://github.com/docker/for-linux/issues/382</a>
